E4c

Sound Isolating Earphones

The E4c earphone features HighDefinition drivers with Tuned-Port
technology for an ultra-wide frequency
soundstage with brilliant
highs and extended bass.
As the ideal companion
to any portable or home
audio source, the E4c
incorporates the same
precision components
used by professional
musicians to bring
incredibly accurate sound
with remarkable isolation.

WEARING THE EARPHONES

Three popular methods for wearing the earphones are illustrated below.

INSERTING THE EARPHONES
If the earphone seems to be lacking in low frequency response (bass), check
the tightness of the seal between the earphone and your ear, or try one of the
other sleeve options.
Warning: Do not push the earphone sleeve beyond the ear canal opening.

Make sure that the sleeve completely
covers the earphone nozzle. If any part
of the nozzle is exposed, the sleeve is
not properly installed.

CHOOSING AN EARPHONE SLEEVE

CLEANING THE EARPHONE NOZZLE

FULL TWO YEAR WARRANTY

Your earphones come with a selection of sleeves. Make sure the sleeve you
use is easy to insert into your ear, fits comfortably, and is easy to remove from
your ear.

If the nozzle of your earphone is blocked, clean the nozzle using the supplied
wax removal loop.

Foam Sleeves
When using the foam sleeves, compress the sleeve between
your fingers before inserting it into the ear canal. Hold the
earphone in place for about ten seconds while the foam
expands and creates a tight seal.

Triple-Flange Sleeves
If desired, the sleeve nozzle may be shortened. Use sharp
scissors to carefully trim the nozzle to the desired length.

SAFE USE



Use a slow twisting motion to remove the earphones. Never pull
on the earphone cord.



Warning: If a sleeve becomes lodged in your ear, seek skilled
medical assistance to remove the sleeve. Damage to the ear
may be caused by non-professionals attempting to remove the
sleeve.



Prior to inserting the earphone, always recheck the sleeve to
make sure it is firmly attached to the nozzle.



Turn up the volume control only far enough to hear properly.



Ringing in the ears may indicate that the volume level is too high.
Try lowering the volume.



If you connect these earphones to an airplane’s sound system,
listen at low levels so that loud messages from the pilot do not
cause discomfort.



Have your ears checked by an audiologist on a regular basis. If
you experience wax buildup, discontinue use until an audiologist
has examined your ears.



Stop using the earphones if they are causing great discomfort or
infection.
